SPECIFICATION forming part of Letters Patent N0. 747,485, dated December22, 1903.

Application filed February 27, 1902. Serial No. 95,876. (No model.)

To all whom t may concern.-

Be it known that I, WTLLIAM EVANS RoB- ERTs, a citizen of the UnitedStates, and a resident of Newark, in the county of Essex and State ofNew Jersey, have invented certain new and useful Improvements inElectrical Type-Writing Machines, of which the following is aspecification.

My invention relates to type-writing machines; and the object of saidinvention is to provide a simple, rapid, and eflicient typewritingmachine which requires lout little manual lahorto operate and whereinelectricallycontrolled means are employed to bring about an actuation ofvarious of the parts.

To these and other ends which will hereinafter appear my inventionconsists in the construction, arrangement, and combination of partshereinafter described, and particularly pointed out iu the appendedclaims.

In the accompanying drawings, wherein like reference characters indicatecorresponding parts in the various views, Figure l is a vertical centralfront to rear sectional view of one form of type-writing machineembodying my invention. Fig. 2 is a detail perspective View of thetype-carrieractuating device, together with the solenoid which actuatesit and the connection to the escapement mechanism.

Fig. 19 isafragmentary detail side view, with parts broken away, of a portionofthe means for shifting the platen. Fig. 20 is an enlarged detailtransverse sectional view of the same, taken on the line :om of Fig. 19.

In the drawings parts have been omitted and broken away to`oetterillustrate other features of the construction.

I have illustrated my invention in its application to a machine which isessentially the same in many of its features as the No. 6 Remingtontype-writing machine, though it should be understood that the inventionis applicable to various other characters of writing-machines, and tothis end various changes in the construction and operation of themachine may be made without departing from the spirit of my invention.

Referring iirst to Figs. l to I6, inclusive, of the drawings, lindicates the frame of the machine, which is provided with a top plate2, that supports upwardly-projecting studs 3 4L, which carrytraverse-rods 5 and li, respectively, on which a truck 7 of the carriagemoves from end to end of the machine. The truck has operativelyconnected thereto a platen-frame 8, which travels with the truck and isprovided with a revoluble platen 9. 'llie platenframe has a traverse`grooveil roller l0 pivoted thereto and which is adapt- 9 ed to bearupon a shift. rod or rail ll and to move the platen-frame in the usualmanner ina direction transverse to the length of the platen for upperand lower case printing. The sl1iftrail is supported upon arms l2,

IOC.

which are pivoted to a fixed portion of the machine at 13 and areprovided with depending arms 14, that are each connected at 15 to adepending link 16, which is pivoted at its lower end 17 to a lever 1S.The shift-rail is restored to the normal position by a spring 12X,connected at one end to one of the arms 12 and at its opposite end to afixed portion of the machine. The levers 13 are united at their forwardends by a cross-bar 18X, and thus form with the cross-bar a yoke, andthe rear ends of these levers are pivoted at 19 to the frame of themachine, and the yoke as a whole is restored to the normal positionbysprings 2O and 12X.

The top plate may have the usual hangers 21, secured thereto by screws22, and pivoted in each hanger at 23 is a type bar or carrier 24, whichis provided with a plurality of types 25 thereon. The heel of eachtype-bar is connected at 26 to an actuating-link 27, that has a hook orabutment 23 at its lower end, and each actuating-link 27 has one end 29of a contractile spring 30 secured thereto.A The opposite end 3l of eachspring` may be secured to a depending stern of the screw 22, whichsecures the associated type-bar hanger in place, and the tension of eachspring 30 is exerted to draw the lower end of the actuating-link awayfrom its associated type-bar. The actuating-links 27 maybe arranged in acircle, with theirlowerhook-like ends extending below the plane of thelower face of the actuating device or disk 32, and the relation of theparts is such that the hook-like ends 28 of the links are normally outof the path of movement ofthe disk. When, however, any of theactuating-links are moved inwardly around the connection 26 as a pivotalcenter,the lower hook-like end thereof will be brought beneath the lowerface of the actuating-disk, as represented at the right-hand side ofFig. 1 of the drawings. Should the disk be depressed at this time, itwill be understood that the type-bar of the associated link will bemoved to the printing-point, the downward movement of the disk beinglimited by a dxed ring 32. This ring has a cam-face 32h, which iseffective to move the hooked ends of the links outwardly during thedownward movement of the disk, so that they are automatically releasedjust before the type bar reaches the printing position, as representedin Fig. 12, and the momentum of the typebar will bring the type thereonto the printing-point, and the rebound of the bar and its spring 30 willimmediately restore the link and type-bar to the normal position. Theactuating-disk 32 is preferally connected by threaded connections 33 toan insulatingpiece 34, which is in turn connected by a screw 35 to thecore or armature 36 of the solenoid or electromagnet 37. This solenoidis supported upon and insulated from a plate 38, which is secured to theframe of the machine by brackets 39. The core or armature 36 is likewiseprovided with a downwardlybracket 45, that is secured at 46 to the framey of the machine. Pivoted to this lever at 47 intermediate of its endsis a link 43, which has its upper end connected at 49 to a crank-arm 50,which projects from a rockshaft 51 of the dog-carrier 52. The solenoidcore or armature, with the parts connected thereto, and the dog carrierare restored to the normal positionby a spring 53, which is connected atone end 54 to the frame of the machine and at its opposite end to therock-shaft 51. If desired, a separate spring may be employed to aid inthe restoration of the parts to the normal position. The dog rocker 52may be provided with the usual feed-dogs 55, that coperate with anescapement-wheelG, that is operatively connected with a shaft thatrotates in a bearing 57, secured to the top plate of the machine. Theforward end of this shaft is provided with a feed-pinion 53, whichmeshes with a feed-rack 59, carried by the carriagetruck 7. The solenoidcore or armature and the act ual-ing disk ordcvice32 maybe guided intheir Vertical movement by antifrictionrollers 60, carriedin brackets61, that extend from said device, and the antifriction-rollers areadapted to bear on the side walls of the guide 62, which is secured at63 to a supporting and guide plate 64, which in turn is secured to theframe of the machine by screws 65. The plate 64 has guiding-slots 64therein, through which the actuating-links 27 eX- tend, the side wallsof the slots limiting the lateral movement of the links.

Surrounding the actuating-links 27 and circularly arranged on thesupporting-plate 64 is a series of solenoids or electromagnets 66, oneof such solenoids being employed for each actuating-link. Each solenoidis provided with a core or armature 67, that has an insulating-head 63,which is adapted to bear upon the associated actuating-link 27, and whena solenoid 66 is energized the core 67 thereof will force its linkinwardly against the tension of its spring 30, so that the hooklike endof the link will be forced beneath the actuating device 32, and upon thedownward movement of said device the connected type-bar will be moved tothe printing-poin t. During these movements of the parts the hooked endof the selected link will be carried off the edge of the disk Orring 32,so that the hook is released just before the typebar reaches theprinting position, and when the circuit which energized the solenoid 66of said link is broken the tension of the spring 30 of the associatedlink will become effective to restore the core 67 of said solenoid tothe nor` mal position.

The so-called selecting contact-plates 69 are pivoted upon a rod 70 andare suitably IOO IIO

rig

'rer/,ess

insulated from the frame of the machine, and each of these plates isnormally maintained in the elevated position by a spring 71, which issecured at one end 72 to one of 'the plates 69 and at its opposite end73 to the frame of the machine. Secured to and depending from the plates69 are bracket-arms 7e, which are united at their lower ends'by across-bar 75, which extends `beneath a centrally-disposed vibratoryshifting contact-plate 76, that is pivoted upon the rod 70. Thiscontact-plate 76 is secured by angle-irons at 77 to theiorwardly-projecting arms of angle-irons 78, which are secured to thecross-bar 18X, that unites levers 18. It will be understood that adepression of the contact-plate 76 will cause the arms 12 to be vibratedagainst the tension of the spring 12X, thus moving the platen in adirection transverse to its length to bring about a shift of the platenlor upperand lower case writing. Upon reference to 14 and 15 it will beobserved that lost motion may be provided in the link 16 by thearrangement therein shown. Thus, for instance, the lower end of the rod16"L is provided with a crosshead 79, which works within guide-slots ina yoke 80, that is pivoted at 17 to the levers 18, and anexpansion-spring 81 is interposed between lhe yoke and the cross-head.rilhe tension of this springis suflicient to canse a transmission otmovement through the rod 161L to `the arms 12 when the shift-plate isdepressed, and thus effect a shifting movement of the platen. After thefull-shift movement has taken place and the transverse movement of theplaten-frame is arrested a further downward movement of the shift-platewill cause a compression ofthe spring 81, so as to permit the angle-iron78 to contact with the cross-bar 75, thus causing the contact-plates69,to which said cross-bar is secured, to be electrically connected tothe plate 76 and to be forced down or to follow the shift-plate 76during` a still further depression of said plate. One of thecontact-plates 69 is provided with a Contact 82, that is adapted to bearupon the contact 83, which is supported by a bracket 84, that isinsulated at 85 from the machine. This bracket 8i is provided with abinding-post 86, to which a wire 87 is connected, and this wire extendsto a battery 88, and a wire 89 leads from this battery to the solenoid37. The return-wire 99 leads from the solenoid to a binding-post 91,which is carried by a plate 92, to which the contact 82 is secured, and

, this plate 92 is insulated at 93 from the conconstitutes a portion ofa separate and distinct circuit, which is formed by the battery 95, awire 96, a solenoid 66, a wire 97, a contact 98 on the finger of theoperator, one of the contact-plates 69, and the return-wire 94. ln thediagrammatic View shown in Fig. 16 these various circuits areillustrated, each circuit being shown with a separate connection 99 on acontact-plate 69. It should be u ndersiood, however, that these variouswires 94C may be hunched in two groups and the terminals for each groupconnected to a single binding-post on one ot' the contact-plates 69.'lhus it will be seen that one half of the circuits may be made throughone of the contact-plates 69 andthe ot her half made th rough the othercontact-plate 68,01', in other words, that the wires of one haltet' theselectingsolenoids 66 are connected to one of the plates 69 and theother half of the solenoids 66 are connected to the other contact-plate69. lt is merely necessary for the operator to place one of the contacts98 upon a contact-plate G9 when a current will be established toenergize the particular selecting-solenoid 66 for which said contact 98is provided. The energizing of the solenoid 66 will force the core orarmature 67 thereof inwardly, thus moving the hook-like end 28 of theassociated actuating-lin k 27 beneath the actuating device or disk 82.1t will be seen that little labor is required, and no manual movement ofthe parts is necessary to bring about this selection of the type-carrierto be actuated. A slight depression upon the selecting contact.- plate69 at this time will cause the contact 82 thereon to bear upon theassociated contact 83. This will result in energizing the solenoid 37,which will cause the core or armature 86 to be drawn down, together withthe actuating device 32 secured thereto, and the selected type-bar willbe moved to the printing` position. This same movement of thesolenoid-core 66 is effective to actuate the escape/ment mechanism andto permit the carriage to be moved by the usual spring-drum, (not.shown,) when the core moves back to the normal position.

lt is of course immaterial at what point on a contact-plate 69, oreither or them, (because they are electrically connected by the crossbar75 and, in effect, constitute one plate,) a contact 98 bears, so thatthe operator has no need of fixing attention upon a keyboard,as isordinarily the case. 'lhere may be any suitable n umberof contacts 98secured to each iinger-stall or carrier 100, which is adapted to iit thefingers ot' the operator, and each contact is connected in theconstruction thus lar described with a single selecting-solenoid 66. 1nthe present construction the machine is shown provided with seventy-sixcharacters, and these seventy-sir; characters may be selected andprinted by 7the contacts carried by the fingers ot the operator and thecoperation ofthe selecting contact-plates 69 and the shift-plate 76.

Should the operator press upon the shittplate 76 with one ot' thecontacts 0S so as to move said plate from the position shown in Fig. 13to that represented in 1e, lthe platen will iirst be shiftedtransversely bythe mechanical connection, and when the angleirons 7Sreach contact with the bar 75, as shown in 14E, an electrical connectionbetween the plate 76 and the plates 69 will be established and a currentwill pass through a selecting-solenoid to move, the particularactuating-link which corresponds to the selecting-contact 9S on theplate 76 into the path of the actuating device 32. t further depressionof the plate 76, which is allowed by the spring connection in the link10, will cause the plates 69 to be forced down with the plate 76,thereby bringing the contact 82 on one of the plates 69 to bear upon itsassociated contact 83, when the circuit will be closed which energizesthe actuating-solenoid 37. The core 36 will then be drawn down and theparticular' type-bar selected by the contact 98 which bears upon theplate 76 will be moved to the printing position. lt will therefore beseen that the shift-plate 76 is not alone effective to bring about ashift of the platen, but that a movement of this plate will select andoperate the particular type-carrier which corresponds to the contact 98that is brought to bear upon the plate, so that a single depression ofthe shift-plate 76 accomplishes a threefold result-that of shifting theplaten, selecting the type-carrier to be operated, and actuating thetype-carrier. YL/'hen the operator desires to feed the carriage withoutactuating a selecting device and without therefore operatinga type-bar,it is merely necessary to depress the vibratory selecting-plate withoutbringing a selecting-contact 9S to bear thereon. This will yresult inthe contact 82 bearing upon the contact S3, and a current will beestablished through the solenoid 237 and the escapement mechanism willbe actuated. l/l/'hile the actuating device 32 is moved, at this time noprinting` will take place, for the reason that a selecting-solenoid hasnot been energized and all of the hooked ends ol the actuating-links 27will therefore be ont ot' the path oi the disk or ring 32.

Frein the foregoing description it will be understood that thesolencidmagnets 60, their cores 67, and the links 27 constituteselecting means or devices. These are lirst operated to select thetype-bar to be actuated, and the subsequent operation ot the actuatingdevice or disl; 32 will effect an operation ot the selected type-bar.

Upon reference to Fig. Sit will be observed that the various wires 97,which extend from the contacts carried by each finger-stall 100, areunited to term a cable 97X, which passes through a guide 101, and thatthese various cables from the fingers of the operator are united into asingle cable 97, which pa ses through a gnidein a bracelet or support102. This guide maybe formed by a strap 103,

vean-ce which is secured at one end 104 to the body of the bracelet andmay be provided with a clasp member 105 at its opposite end thatcooperates with a clasp member 100, carried by the bracelet. The cable07 is placed in position and the clasp-carrying end of the strap 103 issecured in place and the cable may extend a single cable until itarrives at the machine, where connection is made between the respectivesolenoids and the wires 97, which make up the cable.

ln order that the finger-stalls may be maintained in their proper order,so that each iinger-stall maybe attached to the particular finger forwhich it is intended, it is deemed desirable to provide finger-stallclamps 107 for supporting` the linger-stalls when they are not in use.Upon reference to Fig. 9 it will be observed that these clamps may besecured to the table or support for the machine and that the arrangementthereof is such that the lingers with the iinger-stalls thereon may beinserted in the clamps, as represented in full lines in G. rlhe clamps107 are each constructed with a base portion 10S, through which thescrew 109 may be projected to secn re the clamp in place to a suitablesupport. Each clamp is provided with a rigid arm 110, that has a groove111 therein, and extending from the base 108 are resilient clamping-arms112, which are smooth on their inner face and are spaced apartthroughout their lengths and adapted with the rigid arm 110 to surrounda iinger-stall,as well as to allow an endwise insertion of a'linger-stall in a clamp, as illustrated in Fig. 6. ln order to removethe vnger-stalls, it is merely necessary to insert the lingers with thestalls thereon into their respective places in the clamps, when thecollar or lug 113 on each finger-stall will seat itself within thegroove 111. The lingers may then be withdrawn and the stalls maintainedin the clamps. When the operator desires to place the stalls upon thelingers, it is merely necessary to insert the lingers therein in thesame order in which they were withdrawn and to slightly raise thelingers with the stalls thereon, as indicated in dotted lines in Fig. 6,thus removing the lugs 1123 from their respective recesses 111 and the`ngers may be drawn ont of the clamps with the stalls in place thereon.

1n the modification shown in Figs. 17 to 20 of the drawings the samereference characters are employed to indicate the parts which are thesame those shown in the other ligures. ln this inodilication eachselectingcontact 98 on a linger of the operator is connected to twowires 97, which extend to separate solenoids or electromagni-its 66u.There are likewise two selecting contact-plates 09 ein )loyed in thisconstruction, and each of said plates is provided with a contact S2,that coperat-es with a contact 83, and each of said contact-plates islikewise provided with a binding-post 91, to which the wires 90 areconnected, and these wires are joined IOS IIO

"realise at 90b, and the single branch thereof extends to the solenoid87. A single fixed bracket 84E, which carries the two contacts 83a, isprovided with a binding-post 86, to which is secured a wire 87", thatpasses to a battery 88, and the wire 89 extends from this battery to thesolenoid 37. The terminals`99a of the wires 94 are connected to thecontactplates and extend to a battery 95, and the wires 96n extend fromthis battery to the solenoids 66a. There are likewise provided twoshifting contactplates 76, both of which are constructed in a similarmanner, each being electrically connected at 77 to a metallic plate 78a,which is adapted to cooperate with the lateral extension of abracket-iron 74?, which is secured to one of the contact-plates 69a. Itwillbe understood that the operation of this modified construction isthe same as the construction formerly described, except that eachselecting-contact 98a is adapted to select a plurality of typecarriersby reason of its connection with the plurality of theselecting-solenoids 66, the particular type-bar selected depending uponwhich of the contact-plates 69m the selectingcontact is brought to bearupon. Thus, for instance, if a selecting-contact, as indicated in Fig.17, is brought to bear upon the righthand vselecting-plate then thesolenoid 661 (shown to the right in Fig. 17) will be energized. On thecontrary, if the same selecting-contact 9S is brought to bear upon theleft-hand selecting-plate 69 then the lefthand solenoid 66L (shown inFig. 17) will be energized and the associated actuating-link 27 willhave its hooked end forced beneath the actuating device 32. After theselection has been thus made a depression of the contact-plate tif)awill cause the contact 82a thereon to be brought to bear upon itscoperatingcontactS,thusclosingthecircuittln'ougb the actuating-solenoid37 and causing the actuating device 32 to operate the type-bar throughtheselected link. The upper end of each connectinglink 16X passesthrough an aperture 114C in the depending arm 141, which is connected toeach of the arms 12, that carry the shift-rod 1l. The rod ltiXisprovided at its upper end with a pin 115, which extends to oppositesides thereof and constitutes a stop, which causes the arms 12 14 to bemoved therewith during the downward movement ot' a link 16X, but permitsthe arms 14 to move downwardly independently of said links. This is inorder to permit an independent movement of the shift-plates 7oa atopposite sides of the machine. Thus, for instance, when the shittplateupon one side of the machine is depressed it will cause the shift- -rail11 to be moved through the intermediate It should be understood that anydesired number ot' contact-plates 69 may be employed and that thegreater the number of shiftplates the greater will be the reduction ofselecting-contacts carried upon the fingers of the operator. If threeselecting-contacts be employed, then each selecting-contact upon afinger of the operator will be connected with three selecting-solenoidsand each selectingcontact will be available to energize any one of thethree selecting-solenoids in accordance with the contact-plate u ponwhich itis brought to bear.

While I have shown and described with considerable detail two forms orembodiments of my invention, it should be understood that variouschanges in construction and operation may be made without departing fromthe spirit of my invention.
